ArangoDB MCP Server

MCP (Model Context Protocol) is a universal adapter for AI applications, similar to USB-C for devices. This server enables integration between AI applications like Claude Desktop and specific data sources like ArangoDB through a standardized protocol.

Overview: What is the ArangoDB MCP Server?

The ArangoDB MCP Server is a TypeScript-based server designed to provide seamless database interaction capabilities through ArangoDB. It implements core database operations such as querying, inserting, updating, removing, backing up, and listing collections—all via Model Context Protocol (MCP) tools. This protocol ensures that the server can be easily integrated with various AI clients, enhancing their functionality and efficiency.

🔧 Core Features & MCP Capabilities

The ArangoDB MCP Server offers a robust set of features designed to meet the demands of modern AI workflows:

1. arango_query: Executes AQL queries using an AQL query string.

   • Optional bind variables for parameterized queries.
   • Returns results as JSON.

2. arango_insert: Inserts documents into collections.

   • Takes collection name and document object as required parameters.
   • Automatically generates a document key if not provided.
   • Returns the created document metadata.

3. arango_update: Updates existing documents in a collection.

   • Uses collection name, document key, and update object as required parameters.
   • Returns updated document metadata.

4. arango_remove: Removes documents from collections.

   • Requires collection name and document key as parameters.
   • Returns removed document metadata.

5. arango_backup: Backs up all collections to JSON files.

   • Takes output directory path as a required parameter.
   • Creates JSON files for each collection with current data, useful for migration and backup purposes.

6. arango_list_collections: Lists all collections in the database.

   • Returns an array of collection information including names, IDs, and types.

7. arango_create_collection: Creates new collections in the database.

   • Accepts collection name as a required parameter.
   • Optionally specifies collection type (document or edge).
   • Configures waitForSync behavior for write operations.
   • Returns collection metadata, including name, type, and status.

🚀 Getting Started with Installation

Installing via NPM

To install the ArangoDB MCP Server globally, run:

npm install -g arango-server

Running via NPX

Run the server directly without installation using npx:

npx arango-server

Configuring for VSCode Agent

For integration with the VSCode Copilot agent, follow these steps:

1. Create or edit the MCP configuration file:

   • Workspace-specific: Create or edit .vscode/mcp.json in your workspace.
   • User-specific: Optionally, configure mcp-server across all workspaces in your user settings.

2. Add the following configuration to mcp.json:

{
  "servers": {
    "arango-mcp": {
      "type": "stdio",
      "command": "npx",
      "args": ["arango-server"],
      "env": {
        "ARANGO_URL": "http://localhost:8529",
        "ARANGO_DB": "v20",
        "ARANGO_USERNAME": "app",
        "ARANGO_PASSWORD": "75Sab@MYa3Dj8Fc"
      }
    }
  }
}

3. Start the MCP server:

   • Open Command Palette in VSCode (Ctrl+Shift+P or Cmd+Shift+P on Mac).
   • Run MCP: Start Server, and select arango-mcp.

4. Verify the server:

   • Switch to Agent mode in Chat view.
   • Use the Tools button to check availability of arango-server tools.

Installing via Smithery

Automatically install ArangoDB for Claude Desktop using Smithery:

npx -y @smithery/cli install @ravenwits/mcp-server-arangodb --client claude

For specific integration in Claude Desktop and Cline VSCode Extension, refer to their respective documentations.

💡 Key Use Cases in AI Workflows

Real-World Scenario 1: Database Operations in AI Development

Scenario: A software developer is developing a machine learning model using ArangoDB as the backend. They need to easily manage data within their dataset, perform queries and updates, and back up important data for future use.

Implementation: The developer uses MCP to interact with the database from their AI application. By leveraging the arango_query, arango_insert, arango_update, and arango_backup commands, they can integrate these functionalities smoothly into their development workflow.

Real-World Scenario 2: Data Management in Continual Learning

Scenario: A research team is working on an AI system that requires continual learning using ArangoDB for storing various datasets. The team needs to efficiently manage and update data as the model evolves over time.

Implementation: The team employs the ArangoDB MCP Server to handle data operations. By utilizing commands like arango_create_collection, they can add new datasets, use arango_insert to add updated records, and employ arango_backup for safekeeping of historical data. This ensures that their AI models are well-supported by robust data management practices.

🔌 Integration with MCP Clients

The ArangoDB MCP Server is compatible with several key MCP clients:

• Claude Desktop: Supports full CRUD operations on the database.
